 摘要: 采用Chem3D软件自带的分子力学MM2模块对17种4-(1-哌嗪)类香豆素化合物进行几何结构预优化。通过DFT中B3LYP方法在6-31G(d, p)基组水平上对其进行几何构型的全优化。提取Gaussian以及HyperChem软件中相关的量子化学参数并进行相关分析以及回归分析,构建了最优的QSAR模型:lg(1/IC50)=-104.3(±35.203)×ELUMO-0.003 (±0.001) EHF-25.549(±7.278),n=11,R=0.821,R2 = 0.674,R2(cv)=0.593,σ=0.257,F=18.028。

Abstract: The structures of seventeen 4-(1-piperazinyl)coumarin compounds were preliminarily optimized by the molecular mechanics MM2 force field. The structures of the target compounds were totally optimized at the 6-31G (d, p) basis set level by B3LYP method of density functional theory (DFT). The related quantum chemistry parameters obtained from Gaussian and HyperChem softwares were analyzed. The optimum QSAR equation was established as follows: lg(1/IC50)=-104.3(±35.203)ELUMO-0.003 ×(±0.001) EHF-25.549(±7.278),n=11,R=0.821,R2=0. 674,R2(cv)=0.593,σ=0.257,F=18.028.
